[" 9.In Fig "8.61" ,lines "AB,CD" and "EF" intersect at ""O.Find the measures of "/_AOC" ,"/_COF" ,"],[/_DOE" and "/_BOF" ."]

In Figure,lines AB,CD and EF intersect at O.Find the measures of /_AOC,/_COF,/_DOE and /_BOF

Two lines AB and CD intersect at O. If /_AOC+/_AOC+/_BOD=270^(@), find the measures of /_AOC,/_COB,/_BOD and /_DOC.

.In the adjoining figure,three coplanar lines AB , CD and EF intersect at a point O . Find the value of x . Hence, find /_AOD,/_COE and /_AOE

3.In the following figure,the line AB|CD|EF. Find the measures of /_1,/_2,/_3, and /_4

In the given figure, AB CD and EF are three lines concurrent at O. Find the value of y.
